Experimental device may keep trucks from jack-knifing

If there’s one thing that truck drivers don’t want their articulated tractor/trailer rigs to do, it’s jack-knifing. This typically occurs when the tractor skids on the road, and the momentum of the trailer causes it to swing out from behind, ultimately resulting in the tractor and trailer being folded up against one another – not unlike a jack knife’s body and blade. The folded rig usually ends up blocking the road, and the tractor can’t undo the situation under its own power. Fortunately, Greek researchers have recently created a system that they claim could greatly reduce jack-knifing.
